Clinical value of extramural vascular invasion in rectal cancer / 中华放射肿瘤学杂志

ABSTRACT

Extramural vascular invasion (EMVI) is a prognostic factor in rectal cancer. The previous evaluation of EMVI relies on the analysis of postoperative pathological results. With the development of MRI, MRI can accurately assess the status of EMVI (mrEMVI). MrEMVI has become the important prognostic indicator for rectal cancer. The risk of local recurrence and distant metastasis in mrEMVI-positive patients will be significantly increased. The aim of this article is to review the diagnostic features, clinical significance, and impact on treatment patterns of EMVI, and project its future development trend of EMVI.
